In the following detailed description, reference is made to theaccompanying drawings, which form a part hereof. In the drawings,similar symbols typically identify similar components, unless contextdictates otherwise. The illustrative embodiments described in thedetailed description, drawings, and claims are not meant to be limiting.Other embodiments may be utilized, and other changes may be made,without departing from the spirit or scope of the subject matterpresented here.

The present application uses formal outline headings for clarity ofpresentation. However, it is to be understood that the outline headingsare for presentation purposes, and that different types of subjectmatter may be discussed throughout the application (e.g.,devices/structures may be described under processes/operations headingsand/or processes/operations may be discussed under structures/processesheadings; and/or descriptions of single topics may span two or moretopic headings). Hence, the use of the formal outline headings is notintended to be in any way limiting.

Those having skill in the art will recognize that the state of the arthas progressed to the point where there is little distinction leftbetween hardware, software, and/or firmware implementations of aspectsof systems; the use of hardware, software, and/or firmware is generally(but not always, in that in certain contexts the choice between hardwareand software can become significant) a design choice representing costvs. efficiency tradeoffs. Those having skill in the art will appreciatethat there are various vehicles by which processes and/or systems and/orother technologies described herein can be effected (e.g., hardware,software, and/or firmware), and that the preferred vehicle will varywith the context in which the processes and/or systems and/or othertechnologies are deployed. For example, if an implementer determinesthat speed and accuracy are paramount, the implementer may opt for amainly hardware and/or firmware vehicle; alternatively, if flexibilityis paramount, the implementer may opt for a mainly softwareimplementation; or, yet again alternatively, the implementer may opt forsome combination of hardware, software, and/or firmware. Hence, thereare several possible vehicles by which the processes and/or devicesand/or other technologies described herein may be effected, none ofwhich is inherently superior to the other in that any vehicle to beutilized is a choice dependent upon the context in which the vehiclewill be deployed and the specific concerns (e.g., speed, flexibility, orpredictability) of the implementer, any of which may vary. Those skilledin the art will recognize that optical aspects of implementations willtypically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similarimplementations may include software or other control structures.Electronic circuitry, for example, may have one or more paths ofelectrical current constructed and arranged to implement variousfunctions as described herein. In some implementations, one or moremedia may be configured to bear a device-detectable implementation whensuch media hold or transmit device-detectable instructions operable toperform as described herein. In some variants, for example,implementations may include an update or modification of existingsoftware or firmware, or of gate arrays or programmable hardware, suchas by performing a reception of or a transmission of one or moreinstructions in relation to one or more operations described herein.Alternatively or additionally, in some variants, an implementation mayinclude special-purpose hardware, software, firmware components, and/orgeneral-purpose components executing or otherwise invokingspecial-purpose components. Specifications or other implementations maybe transmitted by one or more instances of tangible transmission mediaas described herein, optionally by packet transmission or otherwise bypassing through distributed media at various times.

Insome variants, operational or other logical descriptions herein may beexpressed as source code and compiled or otherwise invoked as anexecutable instruction sequence. In some contexts, for example,implementations may be provided, in whole or in part, by source code,such as C++, or other code sequences. In other implementations, sourceor other code implementation, using commercially available and/ortechniques in the art, may be compiled/implemented/translated/convertedinto a high-level descriptor language (e.g., initially implementingdescribed technologies in C or C++ programming language and thereafterconverting the programming language implementation into alogic-synthesizable language implementation, a hardware descriptionlanguage implementation, a hardware design simulation implementation,and/or other such similar mode(s) of expression). For example, some orall of a logical expression (e.g., computer programming languageimplementation) may be manifested as a Verilog-type hardware description(e.g., via Hardware Description Language (HDL) and/or Very High SpeedIntegrated Circuit Hardware Descriptor Language (VHDL)) or othercircuitry model which may then be used to create a physicalimplementation having hardware (e.g., an Application Specific IntegratedCircuit). Those skilled in the art will recognize how to obtain,configure, and optimize suitable transmission or computational elements,material supplies, actuators, or other structures in light of theseteachings.

For easeof understanding, the flowcharts are organized such that the initialflowcharts present implementations via an example implementation andthereafter the following flowcharts present alternate implementationsand/or expansions of the initial flowchart(s) as either sub-componentoperations or additional component operations building on one or moreearlier-presented flowcharts. Those having skill in the art willappreciate that the style of presentation utilized herein (e.g.,beginning with a presentation of a flowchart(s) presenting an exampleimplementation and thereafter providing additions to and/or furtherdetails in subsequent flowcharts) generally allows for a rapid and easyunderstanding of the various process implementations. In addition, thoseskilled in the art will further appreciate that the style ofpresentation used herein also lends itself well to modular and/orobject-oriented program design paradigms.

Referring to FIGS. 1A and 3 and given by way of overview, anillustrative method 100 (FIG. 1A) is provided for removing carbondioxide from combustion gas 10 (FIG. 3) from an engine 12 (FIG. 3) of avehicle 14 (FIG. 3). The method 100 starts at a block 102. At a block104, carbon dioxide is removed from the combustion gas 10 in a firstvessel. At a block 106, material that contains carbon associated withthe carbon dioxide removed from the combustion gas 10 is stored in asecond vessel. At a block 108, the material that contains carbonassociated with the carbon dioxide removed from the combustion gas isremoved from the vehicle 14. The method 100 stops at a block 110.

The method 100 will be explained first. An illustrative system 200,including its components, will be explained next and the vehicle 14 thenwill be explained. Illustrative details will be set forth below by wayof non-limiting examples.

It will be appreciated that the vehicle 14 may include any type ofvehicle whatsoever that includes an engine 12 which produces carbondioxide emissions that are present in the combustion gas 10 that isexhausted from the engine 12. Accordingly, no limitation to the type ofvehicle 14 is intended and is not to be inferred. Thus, the vehicle 14may include, by way of illustration only and not of limitation: a landconveyance such as an automobile, a car, a truck, a van, a train, a farmimplement such as a tractor or the like, a military vehicle such as atank or a personnel carrier or the like; a water-borne conveyance, suchas a surface ship like a maritime vessel or a pleasure craft or a navalvessel, or a submarine (with a diesel engine); or an aerial conveyancesuch as a fixed-wing aircraft or a rotary wing aircraft.

The engine 12 may be any type of internal combustion engine as desiredfor a particular application. For example, the engine 12 may be aninternal combustion engine that uses a hydrocarbon fuel, such asgasoline or diesel fuel. In some embodiments, the engine 12 may bedisposed in an internal combustion engine in a hybrid vehicle in whichfuel may be switched between a hydrocarbon fuel for the engine 12 andelectricity to power an electric motor. In some applications, fuel forthe engine 12 may be determined by the vehicle 14 in which the engine 12is disposed. For example, in embodiments in which the vehicle 14 isembodied as a submarine, the engine 12 is a diesel engine.

Referring additionally to FIG. 1AK, in some embodiments storing in asecond vessel material that contains carbon associated with the carbondioxide removed from the combustion gas 10 at the block 106 may includestoring in a removably replaceable second vessel material that containscarbon associated with the carbon dioxide removed from the combustiongas 10 at a block 182.

In a related aspect and referring additionally to FIG. 1B, in someembodiments removing from the vehicle 14 the material that containscarbon associated with the carbon dioxide removed from the combustiongas 10 at the block 108 may include removing from the vehicle 14 thesecond vessel.

Given by way of non-limiting example for illustration purposes only, thesecond vessel (that contains carbon associated with the carbon dioxideremoved from the combustion gas 10) may be removed from the vehicle 14and brought to a collection or exchange facility that accepts containers(such as the second vessel) that contain carbon associated with thecarbon dioxide removed from the combustion gas 10. However, it will beappreciated that, in other applications, the second vessel need not bebrought to such a collection or exchange facility.

In some other embodiments and referring additionally to FIG. 1C, ifdesired an empty second vessel may be reinstalled on the vehicle 14 at ablock 114. In such cases, it will be appreciated that an empty secondvessel may be obtained from a collection or exchange facility asdescribed above. Thus, given by way of non-limiting example, in such acase the second vessel (that contains carbon associated with the carbondioxide removed from the combustion gas 10 may be removed from thevehicle 14 at the block 112 and brought to the collection or exchangefacility and exchanged for an empty second vessel, which is reinstalledon the vehicle 14 at the block 114. However, it will be appreciated thatan empty second vessel need not be obtained from such a collection orexchange facility and may be obtained from any source as desired.

It will be appreciated that the carbon dioxide may be removed from thecombustion gas 10 in any manner desired. For example and referringadditionally to FIGS. 1A, 1D, and 3, removing in a first vessel carbondioxide from the combustion gas 10 at the block 104 may includeabsorbing the carbon dioxide in a liquid solution. Given by way ofexample only and not of limitation, the liquid solution may includewithout limitation a chemical solvent absorber, like an alkanolaminesovent such as without limitation monoethanolamine (MEA),methyldiethanolamine (MDEA), diethanolamine (DEA), piperazine,diisopropanolamine (DIPA), diglycolamine (DGA), and/or triethanolamine(TEA). In some embodiments, carbonic anhydrase may be used with thechemical solvent absorber to increase carbon dioxide absorption rates.

Given by way of further examples, in some embodiments the liquidsolution may include amine-modified room temperature ionic liquids(“RTILs”), such as without limitation amine-solubilized RTILs(“RTIL-amines”) and/or amino functionalized RTILs (task-specific ionicliquids, or “TSILs”).

In some other embodiments and given by way of further examples, theliquid solution may include aminoacid metal salts with piperazine. Forexample, the aminoacid metal salt may include without limitationpotassium dimethylaminoacetate. In some other embodiments, the liquidsolution may include amino-amides, such as without limitationdiethylaminoacetamide.

In some embodiments and referring additionally to FIG. 1E, absorbing thecarbon dioxide in a liquid solution at the block 116 may include passingthe combustion gas through a liquid solution at a block 118. In someother embodiments and referring additionally to FIG. 1F, absorbing thecarbon dioxide in a liquid solution at the block 116 may include passingthe combustion gas over a surface of a liquid solution at a block 120.

It will be appreciated that, in some embodiments, the first vessel has afirst pressure and the second vessel has a second pressure that is lessthan the first pressure. In such cases, a pressure differential can helpprevent backflow from the second vessel to the first vessel. Also, insome embodiments (and depending upon the removal modality), a higherpressure may be entailed for removing carbon dioxide than is entailedfor storing carbon dioxide.

In some embodiments and referring to FIGS. 1A, 1D, 1G, and 3, if desiredthe removed carbon dioxide may be separated from the liquid solution ata block 122. Given by way of non-limiting example for purposes ofillustration, the liquid solution may be heated in any manner as desiredto a temperature sufficient to separate the carbon dioxide from theliquid solution, and the carbon dioxide is transferred to the secondvessel for storage. Referring additionally to FIG. 1H, in someembodiments after the carbon dioxide is separated from the liquidsolution at the block 122, if desired, the liquid solution may berecovered at a block 124. For example, the liquid solution from whichthe carbon dioxide has been separated may be cooled in the first vesselfrom its previously-elevated temperature, whereupon the liquid solutionmay once again be used for absorbing carbon dioxide.

In some other embodiments and referring now to FIGS. 1A, 1I, and 3,removing in a first vessel carbon dioxide from the combustion gas 10 atthe block 104 may include adsorbing the carbon dioxide with anadsorption material at a block 126. Given by way of example only and notof limitation, in some embodiments the adsorption material may includewithout limitation activated carbon, a metal-oxide-framework (MOF),silica gel, zeolite, a zeolitic-imidezolate-framework (ZIF), porousmaterial, and/or mesoporous material. In some other embodiments andgiven by way of further examples, the adsorption material may include:RTILs such as imidazolium-based ionic liquids; and/or polymerized roomtemperature ionic liquids (“poly(RTILs)”).

Referring now to FIGS. 1A, 1J, and 3, in some embodiments, if desired,at least one attribute regarding removal of carbon dioxide from thecombustion gas 10 may be determined at a block 128. The determination ofthe attribute at the block 128 may be performed at any point in themethod 100 as desired for a particular application. Given by way ofnon-limiting examples, timing of determination of the attribute maydepend in part on whether the attribute relates to outcome of aprocessing block that has already been performed, whether the attributeis relied upon by any further processing block, or the like. For exampleand referring additionally to FIG. 1K, in some embodiments and ifdesired after the attribute is determined at the block 128, dataindicative of the at least one attribute may be communicated at a block130.

It will be appreciated that the attribute may include any one or moreattributes regarding any one or more aspects whatsoever regardingremoval of carbon dioxide from the combustion gas 10 as desired for aparticular application. Given by way of non-limiting examples, the atleast one attribute regarding removal of carbon dioxide from thecombustion gas 10 may include without limitation any one or more of thefollowing attributes: position of the vehicle 14 where the carbondioxide is removed from the combustion gas 10; time when the carbondioxide is removed from the combustion gas 10; governmental regulationsregarding removing carbon dioxide from combustion gas from an engine ofa vehicle; an amount of pollution in air that is drawn into the engine12; or the like.

It will be appreciated that the material that contains carbon associatedwith the carbon dioxide removed from the combustion gas 10 may includevarious carbon-containing compounds, depending upon whether or not anyadditional processing is performed on the carbon dioxide removed fromthe combustion gas 10. For example, in some embodiments when no furtherprocessing is performed on the carbon dioxide removed from thecombustion gas 10, the material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10 may include carbondioxide itself removed from the combustion gas 10.

In some embodiments and referring additionally to FIG. 1L, if desired ata block 132 the material that contains carbon associated with the carbondioxide removed from the combustion gas 10 may be processed. As used inthis application, “processing” means “reacting with a chemicalreactant.” Accordingly, in some embodiments, processing the materialthat contains carbon associated with the carbon dioxide removed from thecombustion gas 10 at the block 132 may include reacting the materialthat contains carbon associated with the carbon dioxide removed from thecombustion gas 10 with a chemical reactant. For example and withoutlimitation, in some embodiments and referring additionally to FIG. 1M,processing the material that contains carbon associated with the carbondioxide removed from the combustion gas 10 at the block 132 may includetransforming the material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10 into a hydrocarbon,such as without limitation a hydrocarbon fuel, at a block 134. Given byway of non-limiting examples, carbon dioxide may be reacted with naturalgas to produce syngas (carbon monoxide and hydrogen) via “dryreforming”. Given by way of further non-limiting examples, carbondioxide may be transformed to a hydrocarbon via chemical methods and viabiochemical methods.

Regarding chemical methods, chemical transformations of carbon dioxidestart with CO₂ (not CO₃ ²⁻, such as soluble carbonate salts like NaHCO₃and Na₂CO₃), so (if carbon dioxide has been adsorbed) adsorbed carbondioxide is first released from the adsorbent (such as by heating orunder reduced pressure). Illustrative chemical methods may include,without limitation, transformation of carbon dioxide to methanol. Invarious embodiments, transformation of carbon dioxide to methanol may beaccomplished via illustrative chemical methods such as withoutlimitation catalytic hydrogenation (such as under high temperature andhigh pressure or via reduction of CO₂ with a silane using a stableN-heterocyclic carbene organocatalyst to produce a methylsilyl etherwhich is subsequently hydrolyzed to yield methanol). In anotherillustrative chemical method, electrochemical reduction of CO₂ inaqueous media generates CO and H₂ at the cathode in a ratio ofapproximately 1:2 while producing O₂ at the anode, and the generated COand H₂ at the cathode are subsequently reacted to form methanol. Inanother illustrative chemical method, in a photoelectrochemical reactionreduction of CO₂ occurs at a p-type semiconductor electrode with ahomogenous pyridinium ion catalyst using light energy.

Further illustrative chemical methods may include, without limitation,transformation of carbon dioxide to methane. In various embodiments,transformation of carbon dioxide to methane may be accomplished viaillustrative chemical methods such as without limitation catalytichydrogenation. For example, in an embodiment hydrogenation of CO₂ over aFischer-Tropsch Co—Pt/Al₂O₃ catalyst yields methane as the major producttogether with small fractions of C₂-C₄ hydrocarbons. In someillustrative embodiments, in a solar photocatalytic reaction that usesarrays of nitrogen-doped titania nanotubes sputter-coated with anultrathin layer of a platinum and/or copper co-catalyst(s), exposure ofCO₂ and water vapor to sunlight produces methane as the major product.In other embodiments, an illustrative thermochemical reaction of CO₂ andH₂O yields methane by using reduced samarium-doped ceria that has beentreated with a base-metal catalyst (such as Ni).

Further illustrative chemical methods may include, without limitation,transformation of carbon dioxide to a Fischer-Tropsch product. Given byway of non-limiting example, electroreduction of CO₂ over anun-electropolished Cu-electrode can produce hydrocarbons with adistribution similar to that obtained from the Fischer-Tropsch reactionof syngas.

Illustrative biochemical methods may include, without limitation,transformation of carbon dioxide to isobutyraldehyde and isobutanol. Insome embodiments, genetically engineered cyanobacteria can converteither CO₂ or NaHCO₃ to isobutyraldehyde, and isobutyraldehyde isreadily transformed to isobutanol. In some other embodiments,genetically engineered photosynthetic microorganisms can produceisoprene from CO₂ or CO₃ ²⁻.

As a further example and without limitation, in some other embodimentsand referring additionally to FIG. 1N, processing the material thatcontains carbon associated with the carbon dioxide removed from thecombustion gas 10 may include transforming the material that containscarbon associated with the carbon dioxide removed from the combustiongas 10 into at least one compound chosen from a carbonate and abicarbonate at a block 136. Given by way of non-limiting examples, thecarbon dioxide may be reacted with a hydroxide, such as an alkalihydroxide. For example, the carbon dioxide may be reacted with sodiumhydroxide to form sodium carbonate or sodium bicarbonate or withpotassium hydroxide to form potassium carbonate or potassiumbicarbonate, as desired.

As a further example and without limitation, in some other embodimentsprocessing the material that contains carbon associated with the carbondioxide removed from the combustion gas 10 may include hydrating thematerial that contains carbon associated with the carbon dioxide removedfrom the combustion gas 10 to form carbonic acid. In embodiments inwhich carbonic acid is formed, the carbonic acid may be reacted with acarbonate, if desired.

In short, it will be appreciated that the material that contains carbonassociated with the carbon dioxide removed from the combustion gas 10may be reacted with any chemical reactant as desired.

It will also be appreciated that the material that contains carbonassociated with the carbon dioxide removed from the combustion gas 10may be stored while being processed. However, the material that containscarbon associated with the carbon dioxide removed from the combustiongas 10 need not be stored in order to be processed. Accordingly, in someembodiments, the material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10 may be processedwithout being stored.

In various embodiments the method 100 may include any one or moreadditional process blocks related to the material that contains carbonassociated with carbon dioxide removed from the combustion gas 10 and/orremoval of carbon dioxide from the combustion gas 10. Several exampleswill be given below by way of illustration and not of limitation.

For example and referring to FIGS. 1A, 1O, and 3, in some embodiments anamount of stored material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10 may be measured at ablock 138. The measurement performed at the block 138 may measure volumeand/or weight, as desired for a particular application. It will beappreciated that any measurement technique and sensors may be used asdesired. In some other embodiments and referring additionally to FIG.1P, the amount of stored material that contains carbon associated withthe carbon dioxide removed from the combustion gas 10 may be displayedat a block 140.

In some embodiments and referring to FIGS. 1A, 1O, 1Q, and 3, an amountof storage capacity available for storing material that contains carbonassociated with the carbon dioxide removed from the combustion gas 10may be determined at a block 142. For example, the amount of storedmaterial that contains carbon associated with the carbon dioxide removedfrom the combustion gas 10 (that was measured at the block 138) may besubtracted from the total amount of storage capacity available in anempty second vessel. In some embodiments and referring additionally toFIG. 1R, the amount of storage capacity available for storing materialthat contains carbon associated with the carbon dioxide removed from thecombustion gas 10 may be displayed at a block 144.

In some embodiments and referring to FIGS. 1A, 1O, 1Q, 15, and 3, a rateof storing material that contains carbon associated with the carbondioxide removed from the combustion gas 10 may be determined at a block146. For example, the amount of stored material that contains carbonassociated with the carbon dioxide removed from the combustion gas 10(that was measured at the block 138) may be divided by time that elapsedduring storage of the material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10.

Referring additionally to FIG. 1T, in some embodiments an amount of timeremaining to fill the storage capacity available for storing materialthat contains carbon associated with the carbon dioxide removed from thecombustion gas 10 may be determined at a block 148. For example, theamount of storage capacity available for storing material that containscarbon associated with the carbon dioxide removed from the combustiongas 10 (that was determined at the block 142) may be divided by the rateof storing material that contains carbon associated with the carbondioxide removed from the combustion gas 10 (that was determined at theblock 146). Referring additionally to FIG. 1U, in some embodiments theamount of time remaining to fill the storage capacity available forstoring carbon material that contains carbon associated with the carbondioxide removed from the combustion gas 10 (that was determined at theblock 148) may be displayed at a block 150.

Referring additionally to FIG. 1V, in some embodiments a distancetravelable in the vehicle 14 with the amount of storage capacityavailable for storing material that contains carbon associated with thecarbon dioxide removed from the combustion gas 10 (that was determinedat the block 142) may be determined at a block 152. For example, theamount of time remaining to fill the storage capacity available forstoring carbon material that contains carbon associated with the carbondioxide removed from the combustion gas 10 (that was determined at theblock 148) may be multiplied by speed of the vehicle 14. Referringadditionally to FIG. 1W, in some embodiments the distance travelable inthe vehicle 14 with the amount of storage capacity available for storingmaterial that contains carbon associated with the carbon dioxide removedfrom the combustion gas 10 (that was determined at the block 152) may bedisplayed at a block 154.

Referring now to FIGS. 1A, 1X, and 3, in some embodiments time whencarbon dioxide is removed from the combustion gas 10 may be recorded ata block 156. Referring now to FIGS. 1A, 1Y, and 3, in some embodimentsposition of the vehicle 14 where carbon dioxide is removed from thecombustion gas 10 may be recorded at a block 158. Given by way ofnon-limiting example, position information of the vehicle 14 may beprovided by a global positioning system (GPS) unit or the like.

Referring now to FIGS. 1A, 1Z, and 3, in some embodiments removingcarbon dioxide from combustion gas from an engine of a vehicle at theblock 104 may include removing carbon dioxide from combustion gas froman engine of a vehicle when a combustion gas exhaust rate is less than apredetermined exhaust rate at a block 160. In some cases, thepredetermined exhaust rate may approximately represent a maximum inputrate of combustion gas that can be removed at the block 104, therebyhelping to mitigate inefficiencies and/or buildup of back-pressure.

In some embodiments and referring additionally to FIG. 1AA, at a block162 the combustion gas 10 may be exhausted to atmosphere when thecombustion gas exhaust rate is at least the predetermined exhaust rate.In such cases, combustion gas in excess of that which may be removed atthe block 104 is instead exhausted to atmosphere, which can helpmitigate inefficiencies and/or buildup of back-pressure. In some otherembodiments and referring additionally to FIG. 1AB, at a block 164 thecombustion gas 10 may be stored in a third vessel when the combustiongas exhaust rate is at least the predetermined exhaust rate. In suchcases, the combustion gas 10 that was stored in the third vessel at theblock 164 may be available for processing at the block 104 (that is,removal of carbon dioxide) when conditions permit (such as when theengine 12 is shut down or when a combination of the combustion gas 10from the engine 12 and the combustion gas 10 stored in the third vesselis within processing capabilities at the block 104).

Referring now to FIGS. 1A, 1AC, and 3, in some embodiments dataindicative of removal of carbon dioxide from the combustion gas 10 maybe communicated at a block 166. Given by way of non-limiting example andreferring additionally to FIG. 1AD, in some embodiments communicatingdata indicative of removal of carbon dioxide from the combustion gas 10at the block 166 may include wirelessly transmitting from a vehicle thedata indicative of removal of carbon dioxide from the combustion gas 10.For example, the data indicative of removal of carbon dioxide from thecombustion gas 10 may be wirelessly transmitted via radiofrequencycommunications. In some other embodiments and referring to FIGS. 1A,1AC, 1AE, and 3, communicating data indicative of removal of carbondioxide from the combustion gas 10 at the block 166 may includedisplaying from a vehicle a visual indicator of data indicative ofremoval of carbon dioxide from the combustion gas 10 at a block 170.

Referring now to FIGS. 2A and 3 and given by way of overview, anillustrative system 200 is provided for removing carbon dioxide from thecombustion gas 10 from the engine 12 of the vehicle 10. A vessel 202 isconfigured to remove carbon dioxide from the combustion gas 10 from theengine 12 of the vehicle 14. A vessel 204 is configured to storematerial that contains carbon associated with carbon dioxide removedfrom the combustion gas 10. A removal mechanism 206 is configured toremove from the vehicle 14 the material that contains carbon associatedwith carbon dioxide removed from the combustion gas 10. Illustrativedetails set forth by way of example only and not of limitation will nowbe explained.

In some embodiments, the system 200 and its components may be configuredto perform process blocks of the method 100 (FIG. 1A). For example, thevessel 202 may be configured to perform operations at the block 104(FIG. 1A), the vessel 204 may be configured to perform operations at theblock 106 (FIG. 1A), and the removal mechanism 206 may be configured toperform operations at the block 108 (FIG. 1A). Other components of thesystem 200 may be configured to perform other process blocks of themethod 100. In such cases, process details that have already beendiscussed in the context of the method 100 will not be repeated.

The vehicle 14 and the engine 12 have been discussed above. For sake ofbrevity, their details need not be repeated for an understanding.

Still referring to FIGS. 2A and 3, in some embodiments the vessel 204may be vessel configured to be disposed on the vehicle 14. In someembodiments the vessel 204 may be removable from the vehicle 14, and insome embodiments the vessel 204 may be removably replaceable on thevehicle 14. It will be appreciated that the vessel 204 may be any typeof storage vessel as desired that is removably replaceable on thevehicle 14. Given by way of non-limiting examples, the vessel 204 mayinclude without limitation a bottle, reservoir, tank, or the like. Thevessel 204 may be sized as desired for a particular application. Thevessel 204 may be made from any material as desired for a particularapplication.

Given by way of non-limiting example for illustration purposes only, insome embodiments the vessel 204 (that contains carbon associated withthe carbon dioxide removed from the combustion gas 10) may be configuredto be disposed off the vehicle 14. That is, in some cases the vessel 204may be configured such that the vessel 204 may be removed from thevehicle 14 and brought to a collection or exchange facility that acceptscontainers (such as the vessel 204) that contain carbon associated withthe carbon dioxide removed from the combustion gas 10. However, it willbe appreciated that, in other applications, the vessel 204 need not bebrought to such a collection or exchange facility.

In some embodiments (such as in some of the applications discussedabove), the removal mechanism 206 may include the vessel 204. However,in some embodiments the removal mechanism 206 may include an outletport.

Still referring to FIGS. 2A and 3, the vessel 202 may be any type ofreaction vessel as desired for a particular application. The vessel 202may be sized as desired for a particular application.

Asshown in FIG. 2C, in some other embodiments the vessel 202 may befurther configured to pass the combustion gas over a surface 210 of theliquid solution 208.

In some embodiments the vessel 202 may be configured to separate theremoved carbon dioxide from the liquid solution 208. For example,temperature inside the vessel 202 may be raised sufficiently to drivethe carbon dioxide out of the liquid solution 208, and the carbondioxide can be transferred to the vessel 204 for storage. In some otherembodiments, the vessel 202 may be further configured to recover theliquid solution. For example, the liquid solution 208 (from which thecarbon dioxide has been separated) may be cooled in the vessel 202 fromits previously-elevated temperature, whereupon the liquid solution 208may once again be used for absorbing carbon dioxide.

Referring now to FIGS. 2A, 2D, and 3, in some other embodiments thevessel 202 may be configured to adsorb the carbon dioxide with anadsorption material 212.

The varioussingular/plural permutations are not expressly set forth herein for sakeof clarity.

The herein described subject matter sometimes illustrates differentcomponents contained within, or connected with, different othercomponents. It is to be understood that such depicted architectures aremerely exemplary, and that in fact many other architectures may beimplemented which achieve the same functionality. In a conceptual sense,any arrangement of components to achieve the same functionality iseffectively “associated” such that the desired functionality isachieved. Hence, any two components herein combined to achieve aparticular functionality can be seen as “associated with” each othersuch that the desired functionality is achieved, irrespective ofarchitectures or intermedial components. Likewise, any two components soassociated can also be viewed as being “operably connected”, or“operably coupled,” to each other to achieve the desired functionality,and any two components capable of being so associated can also be viewedas being “operably couplable,” to each other to achieve the desiredfunctionality. Specific examples of operably couplable include but arenot limited to physically mateable and/or physically interactingcomponents, and/or wirelessly interactable, and/or wirelesslyinteracting components, and/or logically interacting, and/or logicallyinteractable components.
